Product Family Description

  • AR Coated to Provide <0.7% Reflectance per Surface for 750 - 1550nm
  • Designed for 0° Angle of Incidence

Plano-Concave (PCV) lenses have one flat and one inward curved surface. PCV lenses have a negative focal length and are used for image reduction or to spread light.

These lenses are available uncoated or with other Anti-Reflection coating options including: MgF2, VIS 0°, VIS-NIR and NIR I.
